The FDA's web site has a list
of recalls related to the salmonella outbreak.

So for now, the FDA advises consumers not to eat commercially prepared
products containing peanut butter or peanut paste, or peanut butter served at
institutions, unless they're sure that those products don't contain PCA peanut
butter or peanut paste.

The FDA reminds consumers to throw out recalled products in a manner that
prevents others from eating those items, and to see a health care provider if
you think you got sick from eating peanut butter.
